1/2 inch Feed and Return line recomendations

I'm adding a Procharger to the Dart and need to upgrade my fuel system. I'm going with a 1/2 inch sending unit in the original location in the tank. I'll also be adding a bung for the return line. Using an electric pump then Need 1/2 inch feed line to the boost referenced pressure regulator.

I'm debating between aluminum lines flared to us AN fittings? Push lock line and AN fittings? Steel braided lines with AN fittings?

I'm new to this and just looking for people's thoughts on cost differences vs benefits ect. Any help is appreciated.
